(01. far-n4)- The present invention relates to improvements in-whatis believed to bea novel float valve'assemblage of the type which is mounted for oper ationatop the discharge end of a conventional flush tank feed pipe and which serves to accommodate the pivoted endo'f' a ball float having a ball float arm of the type commonly employed in a flush tank for automatically cutting off the water supply when a' predetermined water level, in said tank, is attained.

Asis obvious from the accompanying. state ment of theinvention' the ball cock't"o"which theinvention relates is characterized by many and varied types'ofvalveconstructions. As has b'eeen' thesituation" with my predecessors" and othersengaged'in this'line of endeavonitis an essential purpo'se'of the" invention to provide a novel valve casing, seat and valve arrangement which is such as to check the flow of incoming water at the discharge end of the feeder pipe, to momentarily trap it i the casing, and to thus cut down the velocity and consequently attending noises, this by causing the trapped water to discharge downwardly against the surface of the feeder pipe.

More particularly, however, an object of the present invention is to structurally, functionally and otherwise improve upon a similarly constructed float valve assemblage covered in Patent No. 2,426,782, granted to me on the date of September 2, 1947.

Reference being had to the patented construction, this in order to gauge the extent of improvements in refinements herein divulged, it will be seen that novelty is predicated singly and collectively on a novel valve, one phase thereof having to do with a casing comprising a body portion, the top of the body portion being providedwith avalve stem guide and means to accommodate and mount a conventional ball float arm, the basal portion of said casing being provided with a depending skirt-like flange, said flange being externally constructed to provide a tool grip, the interior of the flange being screw threaded, the internal portion of said valve casing, at a point above said screw threaded portion, being formed into an annular shoulder, and a complemental ring, said ring being centrally apertured provided on its top side with an upstanding valve seat nipple and being provided on its bottom with an internally screw threaded collar, the collar being adapted to fit and thread on the upper end of said pipe and constituting the sole means for attaching and supporting the entire valve casing.

Another aspect of the patented invention has to do witha seatring unit in which an;apertured disc is provided, the disc having: a collar fanattachment to the feeder pipe said disc further having a nipple forming avalve-seat, the disc being such that it provides novel means to anchor andsupport thesectiona-l valve casing n By structhral and functional; contrast, novelty in-the instant case is predicated-on asimilar valve unit which is characterized-by; collar and nipple and a disc-like flange whichis-"in turnprovided with apertures, thisflange serving to contact-with and fasten on-an internal flange in anannular sin pd V ,4

nnother phasepfnoyelty-hasto do witha sec, tional valve casing whichis separablyconnect able with the valve seat-unit-or-ring;the;body in cludingan annularand-a-depending -frusto-conical flange which surrounds the upper end of the. feed water pipe, said body portion serving toi accommodate a plug-like cap which serves to accommodate the valve with a renewable seat ele-- ment, and there being an arrangement to accom-- modate a yoke for the ball-float arm.

Other objects and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

Figure l is a top plan View, with portions broken away and shown in section, of a valve construction perfected in accordance with the principles of the present invention;

Figure 2 is a view in section and elevation on the line 2-2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a horizontal section on the line 3-3 of Figure 2, looking in the direction of the arrows; and

Figure 4 is an exploded view showing the essential parts of the valve construction.

Referring now to the drawings by distinguishing reference numerals the feed water pipe, which is a conventional type, is denoted by the numeral 6 and is screw threaded at its upper end as at I to accommodate the valve seat unit 8 and this body comprises a single casting or the like which includes a central internally screw threaded collar 9 threaded on the upper end I, an upstanding nipple I0 constituting the valve seat, and there being a flange I l forming the ring and this being provided with suitable notches constituting vents I2.

The valve casing, which is supported on and surrounds the valve seat unit, is denoted, generally speaking, by the numeral I3 and comprises, as before indicated, an upper annular body portion [4 and a frusto-conical lower flange or skirt portion [5 which surrounds, in spaced relation, the upper end portion of said feed water pipe 6. An annular internal ledge forming flange I6 is provided in the casing and the marginal edge portion of the ring is secured thereto by fastenings l'!.

The casing l3 may be said to include merely the primary parts l4, l5 and I6, and may be looked upon as also including a separable element the cap or plug-like closing cap 18. This is a simple cap with a marginal flange 1811 which is threaded into the upper internally screw threaded portion I4 of the casing body. The cap has a central guide 19 to accommodate a slidable valve element 20 which element protrudes slidably into the casing and is provided with a cup 2| and renewable valve seat or washer 22. This cooperates with the aforementioned stationary seat or nipple ID.

The valve element 20 is operable by and through the medium of a yoke 23 which yoke is pivoted to said element as at 24 and which is in turn pivoted at 25 on a post or lug 26 formed integral with and rising from the valve cap l8. The yoke is provided with a screw threaded socket 27 to accommodate the threaded end of the ball-float rod or arm 28.

These types of valves, valve seats, and valve casings are well known and a similar construction is shown in the aforementioned Patent 2,426,782. It follows therefore that the claim is directed to what are believed to be structural and functional distinctions.

Changes in shape, size, materials and rear- 4 rangement of details and parts may be resorted to in actual practice, so long as they do not depart from the spirit of the invention or the scope of the appended claim, as is well understood.

I claim:

In a flush tank valve assemblage of the class described, a feed water pipe, a valve seat unit comprising an apertured flange, a collar on the under side of said flange, said collar being separably mounted on the upper end of said feed water pipe, said flange having a central upstanding nipple in alignment with said collar and constituting a valve seat, a valve casing comprising an annular body portion internally screw threaded and provided with an internal ledge forming flange, said first-named flange being separably mounted on said ledge forming flange, said casing further including a frusto-conical depending skirt, a plug threaded into the annular body portion, and a valve element mounted in said plug and incluidng a cup having a renewable Washer.
